I don't know if what you mean is the same thing that happens to everyone who doesn't follow directions or not. An accurate description of your error would be needed. A screenshot would be great. You've been around a while. On the file's jome page, you'll find requirements listed. STOP USING THE GREEN DOWNLOAD ARROW. READ the file's hompage for a description of the file, and requirements to use it.
That said, some RF6 models have extra features that can't be recognized by G5. That could be your problem.
